Pierwszenstwo Zgloszenie ogloszono: 10.04.1973 Opis patentowy opublikowano: 31.01.1975 74651 KI. 63c,73 46€,37/06 MKP B60h 3/00 F02m 37/06 Twórcy wynalazku: Waldemar Matych, Ryszard Grynczer, Stanislaw Gumiela Uprawniony z patentu tymczasowego: Waldemar Matych, Ryszard Gry: czer, Stanislaw Gumiela, Wars wa (Polska) Uklad zasilania paliwowego w silnikach szczególnie wysokopreznych Przedmiotem wynalazku jest cisinieniowo-opado¬ wy uklad zasilania paliwowego przy silnikach szczególnie wysokopreznych, w sziczególnoslci ido kli¬ matyzatorów pojazdów samochodowych.Znane uklady zasilania paliwowego (klimatyzato¬ rów przy .silnikach szczególnie wysokopreznych sta¬ nowia oddzielny i samoistny iukladi, w którym ele¬ mentami wymuszajacymi obieg ^paliwa byla pompa tloczaca, umieszczona pomiedzy zbiornikiem paliwa klimatyzatora a rozpylaczem. W uklad zasilania wlaczony byl równiez zgrubny filtr paliwa. Dotych¬ czas stosowany uklad iziasilania paliwowego klima¬ tyzatorów na przyklad; w autobusach mial szereg wad i niedogodnosci. Niepodgrziane i niedostatecznie oczyszczone paliwo zanieczyszczalo uklad paliwowy klimatyzatora powodujac przerwy w -doplywie pali¬ wa ujawniajace sie pirzerwami w ognzewaniu. Nie- podgrzane paliwo w temperaturach minusowych zmienialo swa fizyczna postac przez wytracanie pa¬ rafiny idajac efekt podobny do zamarzania i unie¬ ruchamiajac ogrzewanie. Ponadto pompa byla ele¬ mentem ukladu bardzo czesto uszkadzajacym sie i przez to klopotliwym w eksploatacji. Przy stoso¬ waniu wylacznie filtru zgrubnego paliwa nastepo¬ walo czesto zapychanie isde rozpylacza. Poza jtym zachodzila koniecznosc przy stosowaniu oddzielnych samoistnych wkladów paliwowych tankowanie dlwu zbiorników, zbiornika zasilania silnika glównego oraz zbiornika ukladu zasilania klimatyzatora. 30 Celem wyeliminowania powyzszych wad i niedo¬ godnosci opracowano nowy uklad zasilania paliwo¬ wego, wykorzystujac podgrzane przez podgrzewacz, i dokladnie oczyszczone w filtrach paliwo wyply¬ wajace pulsacyjnie .przez zawór przeplywowy utrzy¬ mujacy stale icisnienie w pompie wtryskowej z ma¬ lym dodatkiem z wtryskiwaczy.Cel ten osiagnieto przez wlaczenie w 'uklad pali¬ wowy silnika lukladlu obiegowego zasilania paliwo¬ wego klimatyzatorów.Przedmiot wynalazku izostal uwidoczniony w przy¬ kladowym wykonaniu ma rysunku przedstawiaja¬ cym schemat ukladu.Uklad zasilania paliwowego klimatyzatorów przy silnikach szczególnie wysokopreznych wedlug wy¬ nalazku, wlaczony jest w obieg paliwowy silnika z glównym zbiornikiem 1 i sklada sie z przeplywo¬ wego zaworu 2 umieszczonego miedzy zbiornikiem 3 a zbiornikiem 1 ioraz z odpowietrzajacego zaworu 4 umieszczonego przy zbiorniku 3, do którego wlaczo¬ ne jest paliwo plynace z pompy iwtryskowej uprzed¬ nio podgrzane i oczyszczone w filtrach. W ten spo¬ sób zbiornik 3 uzupelniany jest przewodem nad¬ miarowym, natomiast nadmiar paliwa powraca prze¬ wodem do zbiornika glównego 1.Uklad wedlug wynalazku pracowac moze jako uklad icisnieniowo-opadowy. Zbiornik 3 umieszczo¬ ny nad klimatyzatorem. W czasie pracy silnika uklad paliwowy 'pracuje jako cisnieniowy. Stale cisnienie utrzymuje zawór 2. Po zgaszeniu silnika zaworek 74851I 74651 odpowietrzajacy 4 likwiduje w zbiorniku 3 podcis¬ nienie i kliimatyziatoir jesit zasilany opadowo.Uklad powyzszy moze równiez pracowac jako uklad cisnieniowy. Uimiesziczieinie zbiornika 3 obo¬ jetne. Zastosowano jedynie ziaworek 2 utrzymujacy stale cisnienie. Uklad pracuje cisnieniowo jedynie w czasie pracy .silnika.Ponadto uklad wedlug wynalazku moze pracowac jako uklad opadowy. Zbiornik umieszczony nad kli¬ matyzatorem. Zastosowano jejdynie zaworek 4, któ¬ ry przy cisnieniu paliwa ziamyka sie a przy .podcis¬ nieniu otwiera. Uklad pnacuje w czasie pracy silni¬ ka jak i przy zgaszonym .silniku.Uklad zasilania moze byc wykorzystany do róz¬ nych icelów np. do ogrzewania pojazdów, do zasila¬ nia innych silników, urzadzen itp.Uklad w zastosowaniu do zasilania klimatyzato¬ rów wedlug wynalazku mioze znalezc zastosowanie 10 15 w pojazdach mechanicznych w szczególnosci auto¬ busach, lokomotywach spalinowych, silnikach sita- cjonalnych, pojazdach roboczych. PL PLPriority Application announced: April 10, 1973 Patent description was published: January 31, 1975 74651 KI. 63c, 73 46 €, 37/06 MKP B60h 3/00 F02m 37/06 Inventors: Waldemar Matych, Ryszard Grynczer, Stanislaw Gumiela Authorized by a temporary patent: Waldemar Matych, Ryszard Gry: Czer, Stanislaw Gumiela, Wars wa (Poland) Fuel supply system in particularly diesel engines The subject of the invention is a pressure-drop fuel supply system for particularly diesel engines, in particular for automotive air conditioners. a self-contained system, in which the elements forcing the fuel circulation were a pressure pump, placed between the air conditioner's fuel tank and the sprayer. The power supply system also included a coarse fuel filter. Until now, the fuel supply system for air conditioners, for example, was a number of disadvantages and inconveniences .. Unheated and insufficiently cleaned fuel contaminated the fuel system of the air conditioner causing interruptions in the fuel supply manifested by fringes in the heating element. The unheated fuel at subzero temperatures changed into its physical form by the deposition of paraffin, having an effect similar to freezing and disabling heating. Moreover, the pump was an element of the system which very often damaged itself and therefore was difficult to operate. Frequent clogging of the atomizer core occurred with the use of only a coarse fuel filter. Besides, it was necessary, when using separate self-contained fuel cartridges, to refuel two tanks, the main engine supply tank and the air conditioner supply tank. 30 In order to eliminate the above drawbacks and inconveniences, a new fuel supply system was developed, using the fuel heated by the preheater and thoroughly cleaned in the filters, flowing in pulses through the flow valve maintaining constant pressure in the injection pump with a small addition of This objective was achieved by including in the fuel system of the engine and the circulation fuel supply of air conditioners. The subject of the invention is also shown in an exemplary embodiment of the drawing showing a diagram of the system. Fuel supply system of air conditioners in particularly diesel engines according to of the invention, it is connected to the fuel circuit of the engine with the main tank 1 and consists of a flow valve 2 placed between the tank 3 and the tank 1, and a vent valve 4 located at the tank 3, to which the fuel flowing from the pre-injection pump and the injection pump is connected. ¬ nio heated and cleaned in filters. In this way, the tank 3 is supplemented with an overflow conduit, while the excess fuel returns via a conduit to the main tank 1. According to the invention, the system can work as a pressure-drop system. Reservoir 3 located above the air conditioner. While the engine is running, the fuel system operates as a pressure fuel. Valve 2 maintains constant pressure. After the engine is turned off, the vent valve 74851I 74651 relieves the pressure in the tank 3 and the air conditioner is fed by rainfall. The above system can also work as a pressure system. The temperature of the reservoir 3 is neutral. Only the valve 2 which maintains the pressure is used. The system works in pressure only when the engine is running. Moreover, the system according to the invention may work as a down-slope system. Reservoir placed above the air conditioner. The valve 4 is used, which closes under pressure of fuel and opens under pressure. The system works with the engine running and with the engine off. The power supply system can be used for various purposes, e.g. for heating vehicles, for powering other engines, devices, etc. The system is used to supply air conditioners according to The invention may find application in motor vehicles, in particular buses, diesel locomotives, sieve engines, and work vehicles.
